Dr Adequate writes:There's no reason
a priori why we can't observe the effects of the supernatural.
I am inclined to disagree with that.
It is not as if the world were divided into two fixed realms, the
natural and the
supernatural, and that thus far we only have evidence of the natural. Rather, it that whenever there is evidence, we call that natural, and we relegate the term "supernatural" for that for which there is no evidence.
Dr Adequate writes:We can perfectly well imagine a god who constantly sent squads of angels to Earth to go about singing his praises and smiting wrongdoers. We'd notice.
Yes, we would indeed notice. And we would call that a natural phenomenon. So we would not consider it to be evidence of the supernatural.
